Original applicationrled July 12, 1911,

To all whom et may concern:

Be it known that I, CHRL'ES C. STUTZ,

residing at Norwood, in the Vcounty of Halmilton and State of Ohio, a citizen of the United States, have invented'on discovered certain new and useful Improvements in Manufacture of .Glass Articles, of which improvements the following is'a specilication.

In an application filed by me July 12th, 1911, Serial No. 632735, of which this application is a division, is described and claimed mechanism fon transferring molten glass Vfrom a receptacle to a mold vor seriesI of molds and also for charging the mold or molds from the glass so transferred.

The invention described herein relates to the combination and arrangement of blank and blow molds or a series of such molds with mechanism for shifting and opening and closing such molds.

While preferring to employ the glassy transferring and feeding mechanism as set blow mold in blowing position; Fig. 3 is a sectional elevation on a -plane indicated by the line III-III Fig. et showing the blank mold in receivinol positionyFifr. 4 is a sectional plan view on av plane indicated by the line IV--IlvVv Fig. l Figs.` 5 and 6 are detail views illustrating 'a modification of the.

means employed for tilting the bottom of the blow mold.

In .the practice of my invention it is preferred that. the glass be conveyed from a suitable receptacle to the blank mold by a ladle 9 in the manner shown and described in application Serial No. 632735 but` other suitable means may be employed for charge ing this mold.

The blank mold 76 and blow mold 77 are formed in two vertical sections which are movably mounted on rails 78 arranged above and at right angles to direction of movement `of the ladle. Flach rail consists of stas Specificationy of Letters Patent.

tionary end section b and laterally movable middle section a as shown in Figs. 1, 2, 3, and 4. The middle sections a of the rails site directions. These slides maybe shifted by any suitable means, as for example pin-l ions 80 intermeshing with the teeth on the slides, said pinions being secured on the shafts 81 to which are secured pinions 82 intermeshing with racks 83. have their lowerends attached to movable plates 84 mounted on rods 85 Aand are held in'normal positions by springs 86. The

lower ends of the rods are 'connected by cross heads 87 to the strapsv of eccentrics'88 on the driven shaft 89 as shown in Fig. 1. The end sections b of the rails are arranged a distance apart proportional tothe desired separation of the mold sections necessary for removing the mold sect-ion from around the shown in Figs. 3 and 1.

As the formation of the blank and the blowing of the latter are effected in thel respective molds when carried by the movable rail sections a, provisiontk is made for shifting one mold from and the other mold onto saidrails sections. ably effected simultaneously, and while any suitable means may be employed for that purpose the construction shown in Figs. 1, 2, 3, and 1 is well adapted therefor. Sliding l of the mold sections, that when the latter are; moved outwardly by the slides 79, they will engage the bars-90 and 91 in any suitable of the blank mold will be tied to the corresponding sections of the blow mold. This engagement maybe effected by pins 92 on the bars or tie rods entering holes formed in the mold as shown. tands 93 .and 94 are connected to the en of these barsor tie rods and extend over guide pulleys 95 Vto drums 96 on the driven shafts 98 as shown ain Figs. 1 and 2. By oppositely rotating these shafts'the molds can be shifted, one from and the other into operative position and by reversing the shafts the positions o'f the molds can be changed.

tions which are so mounted in guides on the are attached to slides 79 movable in oppo bla-nk and finished article respectively as bars 90 and 91 are mounted on any suitable bearing parallel withthe rails 78 and are so arranged relative tothe opening movement nia-nner, and when so engaged the sections Serial No. 632,735. Divided and this application led July 19,

Serial No. 639,459. l

These racks l The movements are prefer The neck mold 100 is formed in two secy' under side of the lower bridge 101 as to be movable toward and from each other as hereinafter described. The bridge 101 as also the upper bridge 102 are supported on uprights 103, the lower bridge which carries thefneck mold being adjustable on the upriglits so as to permit of the use of molds of different heights. The neck molds are normally held in closed position by springs 104 connected to the respect-ive mold sections by bands or cords 105 which pass over guide pulleys 106 as shown in Fig. 3. As shown, the lower portions of the neck molds are engaged by both the blank and-blow molds and are thereby held in closed position during the formation of the blank and blowing of the latter. The upper end of the open# ing of the neck mold is closed by the plug 10T on the lower end of the hollow plunger 108 which is guided in its movement by sleeves 109 carried by the upper and lower bridges. The lower end of the plug is pron vided with a teat 110 for forming an initial opening in the upper end of the blank. The plug plunger, etc., are kept cool by a fluid entering through the pipe 11'1 and escaping through a port 112.

The plunger is connected by a lever 113 to the piston rod 114: of a fluid pressure cylinder 115 carried by the upper bridge 102. After the formation of the blank the sections of the moldiare separated by shifting the intermediate sections a of. the rails 78 outwardly into line with the stationary end sections b on one of which the blow mold sections are carried. This separation of the blank mold sections leaves the blank suspended from the neck mold in the same position in `which it was formed. When the blank mold sections are inca/ed outwardly they engage one end of the bars 90 and 91, the opposite ends of which are at that time `in engagement with the blow mold sections. The shafts 98 are now operated to shift the blank mold from and the blow mold onto the movable rail sections a which are then moved inwardly closing the blow mold sections around the blank, the lower portion of the neck mold and the bottom of the mold. While the blank is suspended from the neck mold, it is preferred that a sufficient puff of air be admitted into the lower end of the tubular guide 109 through a port 117 to enlarge the initial opening formed in the upper end of the blank by the teat 110,:y

the plunger having been raised at about the time the blank mold sections were sepa` ratedby the admission of fluid pressure into thecylinder 115, to uncover the port 117 and "permit the air to enter the neck mold.

The bottom 118 of the blow 'mold is carried by the bar 119 slidably supported in lugs 120 attached to the mold sections shown in Figs. 5 and 6. lnA order to hold the bottom central. during the movement of the sections, springs 116 are secured to the bar 119 the springs being so constructed as lo bear against surfaces 121 of the machine as shown in Fig. 5. The bottom 118 is norinally held in horizontal position by an arm 122 secured to the bar 10 and provided with a. pin' or roller projecting into a guide groove 123, as shown in Figs. 1 and 2. The guide groove is provided with an angular portion which will shift the arm and bottom of the blow mold thereby causing the bottle to tilt and drop off the bottom as the blow-mold reaches its position on the end sections b of the rail 78. In Figs. 5 and 6 is shown a modification of the bottom tilting means permitting the bottle to remain on the bottom and cool until the blow mold is moved to central position for the blowing of the next blank. The guide groove 12st is provided with a V shaped depression in which is located a two armed switch. This switch is normally held by a spring with one arm e in such position that when the blow mold is moving from central position the pin on the arm 122 will pass over the part c lholding the bottom horizontally. TWhen the mold is returned to central position the pin on the arm 122 will be deflected down into the V shaped depression by the part f turning the bottom so that the bottle will drop off. After the blow moldhas been closed as stated suilicient air under pressure is admitted through port 117 to fully expand the blank. After blowing has been completed the slides 79 are shifted moving the blow mold sections apart and bringing the rail sections (L into alinement with the end sections b. 1n their movement apart projections 125 on the blow mold sections strike against lingers 126 pivotally mounted on the neck mold sections and move the latter apart. thus leaving the completed article entirely free and resting on the bottom 11S as shown in Fig. The shafts 0S are now operated to shift the blow and blank mold sections the latter into central or operative position. As the blow mold sections move away from central position the projections 125 pass away from the fingers 126 permitting the neck mold sections to be closed together by their springs 101. By reference to Fig. l it will be noticed that the'projections 12S are made of such length that neck mold sections will not be free to be moved by the springs until thebottle has been moved sufficiently far by the bottom of the blow mold to be entirely clear of the neck molds when snapped shut by their springs. The shaft 72 is now operated in reverse dircction to shifty the blank mold sections to gethcr and around the lower ends of the neck mold sections.

ll'hen employing the method of charging the blank mold described and shown in said application the ladle is raised until the effected by replacing the lower end of the blank mold is immersed in the. molten glass a portion of which is caused to low iip and lill the blank mold. The ladle is then lowered and the glass in the mold severed from that remaining in the ladle. While any suitable means may he employed forthus severing the glass, that shown is suitable.

Rails 68 aresecured to the side plates ot the machine in a suitable relation to the blank mold, and on these rails is mounted the knife carriage 69, connected by the link 70 to a crank arm preferably secured on the countershaft 71 which is driven suitable l intervals by the shaft '72 as shown in Figs. l 1 and c. The carriage is provided with an l abutment 73 and a strap 74 through the top of which passes a set screw. The `blade 5 which isl provided at its rear end with an l in any direction but is blown and shaped in the place it 'was formed.

It will be understood that as regards the broad features c claimed as of the invention herein, the mechanisms shown and described are merely types and that such mechanisms can he readily changed and modified within wide limits by one skilled depart-ing from the spirit of the invention.

l claim herein as my invention;

l. ln a machine for the manufacture of glass articles, the combination of a relatively stationary neck mold and blowing means connected thereto, and 'blank and blowing molds, movable into operative relation relative thereto.

- 2. In a machine :tor the manufacture ot' glass articles, the combination ot a .neck mold, a blank mold, a blow mold and means for simultaneously' shitting said blank and blow molds one into the'other away from operative relation to the neck mold.

'3. ln a machine for the manufacture of glass articles, the combination ot a neck mold, a blank mold, a blow mold, means for shi ting said blank and blow vmolds alternately into operative relation' to the neck mold and means for opening and closing the sections of' said molds. Y

et. In a machine tor the glass articles, the combination of rails having intermediate movable sections, a mold having its sections movabl'y mounted on said rails and means for mov-ing the intermedi.- ate rail sections into and out of alinement with the other sections. i

5. In a machine for the manufacture of glass articles, the combination of rails having. movable intermediate sections, a mold having its sections mounted on said rails', means for shitting the mold alongv the rails and means tor moving adjusting screw '75a is passed'under the strap and over the abutment which serves 'as a pivotal support for the blade. By means ot' the screws the front end of the blade can he closely adjusted so that when the carriage is reciprocated the blade will move along in Contact with the lower end ot" the lblank l mold making a clean cut through the glass. As will be readily seen by reference to Fig. l 1 the blade can be easily removed by loosening the screw in the strap 74. l The shafts 72, 89 and 9S may be driven in l any suitable manner as will suggest itself to one skilled in the art, but preferably in the manner shown and described in tie ap plication referred to. The shafts 98 should be driven simultaneously butin opposite directions.

lt will be readily understood that the blank and blow mold and neck molds can 1 he easily and quickly removed and other molds substituted without changing the adfii-itment ol' any of the other parts of the machine except the bridge 101 carrying the neck molds and the plunger for closing the l 6. in a machine for the manufacture of upper end of the latteigavhen the substil glass articles, the combination ot rails havend sections.

tuted molds vary in length from those removed. The adjustment of the bridge is ing moil'ahle intermediate sections, molds U shaped collarsl 103n on the upright 103. 4It will lie. observed means for simultaneously shifting said mold that those parts whose sections along the rails, and means for moving the intermediate rail sections out of and into alineinent with the end sections.

movements would vary with diiierent sizes of molds, are actuated by mechanisms having springs or cushions in their connections and hence by i adjusting the actuating mechanisms to give thc greatest movement likely to be needed the springs will yield and compensate for l lesser movements.

As will be readily understood by those skilled in the art any shifting of the blank l while/hanging from the neck mold free and l laterally unsupported will tend to bend the upper portion of the still plastic blank.
